<h2>外掛總結：</h2>
<p>網頁內容創建的無障礙性是至關重要的。許多組織必須遵守嚴格的 WCAG（Web Content Accessibility Guidelines）要求。盡管 Gutenberg 區塊編輯器顯著增強了內容管理，但仍允許發佈可能不符合基本無障礙性標準的內容。這個外掛提供了可配置的區塊檢查，讓網站擁有者和內容編輯可以執行。這些檢查可以強制執行嚴格的無障礙性錯誤通知以防止發佈，或在編輯器中提供警告，仍然允許發佈。</p>
<h3>外掛檢查內容：</h3>
<ul>
<li>core/button: 檢查每個按鈕上的文本和連結</li>
<li>core/heading: 防止在內容中使用一級標題</li>
<li>core/gallery: 檢查圖像的替代文本</li>
<li>core/image: 檢查圖像的替代文本</li>
<li>core/image: 添加切換開關以確認將圖像用作裝飾元素，從而繞過無障礙性檢查</li>
<li>core/table: 檢查每個個別表格區塊上的表頭行</li>
</ul>

原文外掛簡介
Block Accessibility Checks is a comprehensive WordPress plugin that proactively prevents accessibility issues in your content before they reach your audience. Designed for the Gutenberg block editor, it provides real-time validation with a three-tier system that ensures your blocks, post meta fields, and overall document structure meet WCAG (Web Content Accessibility Guidelines) requirements.
Unlike reactive accessibility tools that scan published content, this plugin catches problems during the editing process—giving immediate visual feedback and preventing publication of content with critical accessibility errors. Content creators get clear guidance on what needs fixing, while developers can extend the system with custom checks for blocks, meta fields, and editor-level validation.
Whether you’re a content creator ensuring your posts are accessible, a developer building accessible blocks, or an organization maintaining compliance standards, Block Accessibility Checks provides the tools you need to create inclusive content effortlessly.
Features for Content Creators & Editors:
Real-time Visual Feedback – See accessibility issues instantly with color-coded borders (red for errors, yellow for warnings) around problematic blocks and detailed error messages in the block inspector panel
Smart Publishing Control – Critical accessibility errors prevent publishing until resolved, while warnings allow publication with user awareness
Comprehensive Block Coverage – Built-in validation for images, buttons, tables, headings, and galleries with clear guidance on how to fix issues
Document-Wide Validation – Advanced heading hierarchy checking prevents skipped heading levels and ensures proper content structure across your entire post
Title Validation – Ensures posts and pages have a title set for accessibility and SEO, validates in real-time as you type
Intelligent URL Validation – Real TLD validation using the Public Suffix List ensures only legitimate domains are accepted in button links
Configurable Settings – Control which checks are errors (prevent publishing), warnings (allow with notice), or disabled through an intuitive admin interface
Grouped Error Display – All accessibility issues shown at once in organized groups, eliminating the “fix one, see another” frustration
Works Everywhere – Validation runs in both the post editor and site editor (templates/template parts) with separate configurable settings
Features for Developers & Plugin Authors:
Three-Tier Validation API – Register custom checks for block attributes, post meta fields, and editor-level validation using comprehensive hooks and filters
JavaScript-Only Validation – All validation logic runs in JavaScript for real-time editor feedback without server round-trips
Automatic Settings Integration – External plugins automatically get their own settings pages under the Block Checks menu
External Plugin Support – Works seamlessly with custom blocks from third-party plugins and themes
Extensive Hook System – 20+ action and filter hooks for complete customization of registration, validation, and display behavior
Well-Documented API – Complete developer documentation with quick start guides and working code examples
How It Works:
The plugin provides immediate feedback as you edit content through a sophisticated three-tier validation system:
Block Validation – Validates individual block attributes in real-time as you type and edit
Meta Field Validation – Checks required post meta fields with automatic post locking when validation fails
Editor-Level Validation – Validates document-wide concerns like heading hierarchy that span across multiple blocks
When accessibility issues are detected, they are highlighted with visual indicators (red for errors, yellow for warnings) and detailed messages explain how to fix the problems. Critical errors prevent publishing until resolved, while warnings allow publication with user acknowledgment.
Built-in Accessibility Checks:
Button Blocks – Ensures buttons have descriptive text content and validates link destinations using real TLD validation (Public Suffix List)
Image Blocks – Requires alt text (unless marked decorative), validates alt text length (warns if exceeding 125 characters), prevents caption duplication, and detects non-descriptive patterns like “image of” or “photo123”
Table Blocks – Requires proper headers or captions for screen reader navigation
Heading Blocks – Validates proper heading hierarchy across entire document (prevents skipped levels), ensures appropriate first heading level (H2 recommended, H1 allowed with warnings), and provides configurable heading level restrictions (H1, H5, H6 can be disabled)
Gallery Blocks – Applies comprehensive image accessibility checks to all gallery items (alt text, length, patterns, caption duplication)
Post & Page Title Validation – Ensures posts and pages have a title set for accessibility and SEO, validates in real-time as users type, prevents publishing content without a title, configurable independently for posts and pages
Post Meta Fields – Validate required custom fields with real-time validation, automatic post locking for errors, and seamless integration with block validation system
Perfect For:
Government websites requiring WCAG compliance
Educational institutions with accessibility mandates
Businesses committed to inclusive web content
Developers building accessible WordPress themes and plugins
Content teams who want accessibility guidance built into their workflow
Developer Resources:
Extend the plugin with custom accessibility checks using the comprehensive validation API. See the complete developer documentation for quick start guides, API reference, code examples, and a working example plugin.
